PURPOSE: To improve the efficiency of the metering job by allowing a master set side to discriminate it when no measurement data is obtained from the meter in the radio metering system where a slave set sends data to the meter via an electric connection component when a transmission request signal is received through a radio channel from a master set and measurement data received from the meter are sent from the slave set to the master set so as to detect the measurement result. CONSTITUTION: An information control means 20 sending it to a master set 10 when it is discriminate that no measurement data are obtained from a meter 13 is provided to a slave set 11. Then in the case of remote metering, when it is discriminated that no measurement data are obtained from the meter 13, it is sent to the master set 10 through a radio channel to distinguish information denoting no measurement data of the meter from other metering error information. |
